I was observeing the trifid nebula in the constellation sratigus with an antares 12inch dobsonian telescope when i caught sight of an object that was an orange color and what appeared to be orbiting the earth. It was very high up; most likley out of the earths atnosphere. The object was pulsating to different magnitudes(brightness); and kept changing speeds. At one piont it atmitted a bright orange beam for about 3 seconds. About 2 minutes later, the object started to decrease altitude. As it was doing so, it started to get fainter and and started to pulsate brighter and then dissapeared. the object could not be seen with the naked eye or through the scopes 8x52 view finder. The lens i used to view the object was a plossl 1.25in 32mm with on the scope i was useing was about 50x. there was one more witness. My dad got a quick glimpse of the object. It had no visible shape. I know it wasnt a satellite or a meteor because satilites dont pulsate and the bject was goining to slow to be a meteor.
